The 6-71 is an inline six cylinder diesel engine. [1] The 71 refers to the displacement in cubic inches of each cylinder. [1] The firing order of the engine is 1-5-3-6-2-4. [1] The engine's compression ratio is 18.7:1 with a 4.250 inch bore and a 5.00 inch stroke. [1]
It was the first calculator that could perform all four basic arithmetic operations. [ 3 ] Its intricate precision gearwork, however, was somewhat beyond the fabrication technology of the time; mechanical problems, in addition to a design flaw in the carry mechanism, prevented the machines from working reliably.
A HP-71 configuration with bar code wand and a custom application was widely used for data collection in the British Department of Health and Social Security (DHSS). Unlike HP-75 or HP-41 , the 71B could also act as a device in a HP-IL loop controlled by another device, allowing several of them in the same loop, communicating with each other ...
The second one was a programmable mechanical calculator, his analytical engine, which Babbage started to design in 1834; "in less than two years he had sketched out many of the salient features of the modern computer. A crucial step was the adoption of a punched card system derived from the Jacquard loom" [12] making it infinitely programmable ...
On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown. [ 1 ] [ 2 ] [ 3 ] On an expression or formula calculator , one types in an expression and then presses a key, such as "=" or "Enter", to evaluate the expression.

The Zenith STOL CH 701 and CH 750 are a family of light, two-place kit-built STOL aircraft designed by Canadian aeronautical engineer Chris Heintz through his Midland, Ontario, based company, Zenair.
The Alfa Romeo 6C 1900 was the final derivative of the original 6C 1500, produced in 197 examples during 1933 as a transitional model, before the new 6C 2300 was introduced the following year. [21] Only built in Gran Turismo guise with a 2,920 mm (115.0 in) wheelbase, the 6C 1900 replaced the corresponding 6C 1750 model. [ 22 ]
After Dalton's death, Weems [5] updated the E-6B and tried calling it the E-6C, E-10, and so forth, but finally fell back on the original name, which was so well known by 50,000 World War II Army Air Force navigator veterans. After the patent ran out, many manufacturers made copies, sometimes using a marketing name of "E6-B" (note the moved ...
